To all lLai/7mm t may Concern Be it known that I, WILLIAM GIFFORD Jones,a citizen of the United States, residing at Evanston, in the county ofCook and State of illinois, have invented a neu7 and useful improvementin Loose-Leaf Binders, of which the following is a specification.

This invention relates particularly to loose-leaf binders havingclamping-members joined by flexible connections, or flexiblebinding-posts; and the' primary object of the invention is to providesimple and durable extension means for the flexible bindingposts,whereby the binding-posts can be lengthened at will, Without disturbingthe connections with thev clamping-members of the binder.

The invention is illustrated in its preferred embodiment in theaccompanying drawing, in Which- Figure l represents a brokenlongitudinal sectional vievv of the clampingeme'mbers of a loose-leafbinder, showing the takeeup' mechanisms and the improved flexiblepostconnection betiveen the clamping-members; Fig; 2, a broken sectionalview taken as indicated at line 2 of Fig. l; Fig. 3, an enlarged brokensectional vieWv of the improved flexible post employed; and Figl 4,details of the extension members Tvvith which the ilexible post isequipped at an intermediate point, whereby the post can be lengthened atwill Without disturbing the connections between the ends ofy the postand the clamping-mem;

4bers.

ln the construction illustrated, A, A rep# resent the clamping-'membersof a looseleaf binder, such as a current ledger or transfer binder; B, Brepresent the' take-up mechanisms With which' the clampingmembers areequipped; and C represents an improved flexible connection, or flexiblebind ing-post, connecting the clamping-members.-

ln the illustration given, each oi the links 4t and special links er and4b; a swiveled post-section etc; and any desired number of insertpostesecti'ons ed.,

The chain-post C is preferably of circular cross-section. The links eare short and are close-connected by meansV of small, flat links 5 inthe manner ,disclosed in my Patent No. 1,184,3e9, granted May Q8, 19l6.The special link da is connected by a similar flat link 5 to theadjacent link 4. The special link 4kb is shown provided with aneirtension ear or eye 6 by means or' Which it is connected with theadjacent link e.'

rllhle special link eta is provided at one end with a threaded socket 7;and the special link el is provided with a. bore or socket 8, Thepost-'section e is provided at one end with a reduced extension 9 whichis siviveled in the bore 8 of the link e, being rotatably securedtherein by means of a pin Qivhich engages a circumferential groove 9bwith which the extension 9 is provided. r`llhe postsection Le isequippedat its opposite Ver'id with a reduced threaded extension 10,which is adapted to s'creu7 into the threaded socket 7 of the speciallink 4a.

The insert'post-'sec'tion 4d is provided at one end with an internallythreaded socket 11, and at the opposite end with a reduced threadedextension l2.-

In the illustration given, the insertL poste section 4d has the portion1Q screwed ii'ift the threaded socket 7 of the special link 4a; and thereduced threaded extension i0 of the siviveled post-section le isscrewed into the socket 11 of the insert post-section ed. Any desirednumber of insert post-sections 4d may be interposed between the speciallink La and the post-section 4C, Which has swiveled connection with thespecial link 4b;

The link portions of the flexible post pass about curved bearings 13With which the clamping-members are provided, and extend into theclamping-members, the extremities of the flexible post being firmlysecured to the nuts 2 From the description given, it will be understoodthat the improved flexible post is providedl aty an intermediate pointwith means for receiving` extension inserts, whereby the flexible postmay be lengthened at will without disturbing the connections between theextremities of the flexible post and the clamping-members. In theillustration given, both extremities of the flexible post are connectedwiththe take-up mechanisms of the clamping-members. This is the only,and no unnecessary limitation should be understood therefrom, but theappended claims should be construed as broadly as permissible in view ofthe prior art.

What I claim as new and desire to secure by Letters Patent isl. In abinder, the combination with clamping-members equipped with take-upmechanisms, of a flexible post connected at its extremities with saidtake-up mechanisms and provided at an intermediate point with anextension insert, whereby said post may be vlengithened at will withoutdetachment from saidtake-up mechanisms.

2. In a binder, the combination with clamping-members, at least one ofwhich is provided with take-up mechanism, of a chain-post connecting`said clamping-mem bers and having an extremity connected with saidtake-up mechanism7 said chain-post provided atan intermediate point withlinks adapted to receive post-inserts, whereby said post may belengthened withoutvdisturbing the connections at the extremities.

c 3. In a binder, the combination with clamping-members, at least one ofwhich is provided with take-up mechanism, of a bers and hai/ing anextremity connectedwith said take-up mechanism, said chain-post providedat an intermediate pointwith-links having socket-connections, wherebyinsert post-sections vmay be interposed to enable the chain-post to belengthened without disturbing the connections with theclamping-members.v

4. In ya binder, the combination with clamping-members, at least one ofwhich is provided with take-up mechanism, of a chain-post connectingsaid clamping-members and havingl an extremity connected with saidtake-up mechanism, said chain-post having a link equipped withy aswiveled postsection and having another link adapted for connectioneither with said swiveled postsection or an insertpost-section.

5. In a binder, the combination with clamping-members equipped withtake-up n mechanisms, of a chain-post connected at its extremities withsaid take-up mechanisms, said chain-post having a link equipped with aswiveled post-section and another link provided with a socket, and aninsert post-section between said swiveled post-section and saidlast-named link.

6. In a binder, the combination withl clampingemembers equipped withtake-up mechanisms, of a flexible post connected at its extremities withsaid take-up mechanisms and provided at an intermediate pointwithsocket. connections for receiving insert postsections, and insertpostsections whereby said flexible post may be lengthened withoutvswiveledmember and socketconnections bef` tween said swiveled member andan adjacent link, whereby insert post-sections-may be interposed toenable the chain-post to be lengthened without disturbing theconnections with the clamping-members.
